The better option would be to build an X509Chain object and use the various options available on it to check the validity of the chain including revocation status. .NET doesn't offer any low level APIs to check a CRL directly, so you would need to p/invoke that type of thing in the cryptoAPI if you want to hit it at that low a level. It usually isn't a good idea to try to build this yourself though.
